I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
You would need another forensic pathologist to review the work of the first forensic pathologist.
Best of luck.

Sorry, but I’m not trained in digital forensics. I have absolutely no idea.

I believe it’s a presumptive test, so it would not be considered ‘conclusive’ evidence, only an indication that further test (like DNA) would be appropriate.
I have never used an orthotolidine test, unless that’s the reagent in the Hemastix test strips. We used those a great deal at the coroner’s office—they’re very handy, but can have false positives. Deciding what reagent to use will always be a function of ease of use, possibility of false positives and false negatives, expense and hazards (such as carcinogenic properties).
Best of luck!

Bodies begin to deteriorate immediately, but the process might progress more slowly or less slowly depending on temperature, humidity, exposure or any medical conditions of the victim.

With hairs, you can’t identify one to a specific person with only microscopic examination—the main reason it is hardly used these days, and typically only as screening to decide to do DNA analysis. Then DNA analysis is actually done on the skin cells clinging around the root, because the actual hair doesn’t have any nuclear DNA. It does have mitochondrial DNA though few labs can do that.Fiber analysis is also rarely done these days because it can’t be positively identified to an article of clothing, or is it possible (usually) to find out how many of that article had been manufactured or sold and who they were sold to, etc. An analyst can say the fiber is consistent with coming from that article but that’s all. Unless there is a ‘jigsaw match’, a section of the material found that can be fit back into the article of clothing like a puzzle piece.Hope that helps!

I used to be the hair and fiber analyst. Unfortunately it's increasing rare to find fiber analysis done at labs. Perhaps I can help you.
